RI LWAY-SIGNAL.

SPECIFICATION forming part of Letters PatentvNo. 286,122, dated October2, 1883, Application filed May 12, 1883. (No model.)

.To all whom it may concern:

Be it known that I, HENRY H. EATHERroN, of Montieello, in the county ofPiatt and State of Illinois, have invented certain new and usefulImprovements in Railway-Signals; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same,

io reference being had to the accompanying drawvings, which form a partof this specification, and in whieh Figure 1 is a front View ofmyimproved railway-signal. Fig. 2 is an end view of the same,` and Fig.3 is a front view of one of the signalposts 011 an enlarged scale.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of railway-signale in which thewheels of the passing locomotive strike a lever which sets a signal,which is not changed until the train has passed another similarsignal-post at the end of the portion of the track it is desired to pro-2 5 tect; and it consists in the improved construction and combinationof parts of the same, as hereinafter more fully described and claimed.In the' aecompanying drawings, the letter A indicates a portion of arailway-rail. B B ilidicate two upright posts, placed at the distancedesired to protect by the signals, near the track, and D indicates oneor more npright posts, over which the wires connecting the signals pass.A lever, E, projects upward from a 3 5 rock-shaft, F, rocking inbearings G near the track, and in the lower end of the upright post B,and the said rock-shaft fornis a double crank, H, at its centralportionbetween the bearings, which projects npward in the same 40direction as the lever E, which extends from the nter end of therock-shaft immediately next to the rail. The horizontal portion of thecrank has two springs, I, fastened to it and to the gronnd on both sidesof the crank, serving to retract the crank to its vertical positionafter it'has been tilted by the passing car-wheels; and the crankprojects up into the lower bifurcated end of a lever, J, which ispivoted on the post B and rocks in a vertical plane upon the same, and across-piece, K, is fastened upon its lower end, above its bifurcatedportion, extending to both sides at right angles to the same. The spacebetween the bifurcated ends of the levers J is wide enough to admit ofthe crank returning to its vertical position after having been tilted bythe pass- ,lower end upon the npright B, while its npper end is hingedto another toggle-arm, O, the npper end of which is hinged to adownwardprojeeting arm, P, to the npper end of which a prismatic casing,Q, is fastened, which slides upon the npper end of the npright B, uponwhich a correspondingly-shapcd block, R, is removably placed, which maybe exchanged with a lamp in the night. This block may be colored withany desired color, and it will be seen that as the train passes by thenpright ,i the lever E, which projects slightly above the rail, will bestruck by the wheels of the locomotive and be tilted, which rocks thelever J, and through it the toggle-arms, which slide the casing Q andcover or uncover the signal, as the case may be. Two wires, S and S',are secured to the ends of the cross-pieces K, and pass through p'ulleysT upon the npri'ght B and through pulleys U upon the posts D, to asimilar apparatus at the other end of the portion of track which it isdesired to protect, the wire connected to the one end of the crosspiecebeing` attached at its other end to the end of the other cross-pieceupon the opposite side of the other upright, so that when the one of thesignals has been set/by the passing train in one position the othersignal will be set in the same position by the wires. In this manner itwill be seen that the train in passing one sgnal-post will set both thesiguals simul'taneously, warning the train following it, or a trainmeeting it, that it is on that section of the track, and changing itwhen it arrives at the other s gnal-post, showingthat the track is clearfor that section.

1. In a ralway-signal of the described class,

the combination of the roek-shaft F, having the level' E and doublecrank H, the bifureated slotted lever J, toggle-arm N, having 1115; L,togglearm O, and prisnlatieeasing Q, having` doWnWard-hending ann P, asand for the purpose shown and set forth.

2. The heren-described railway-sgnal, eonsisting of the uprghts B, thelevers E, the

drock -shafts F, forming double eranks H,

springs I, bifureated slotted evel's J, cross- 'eombned,-and arranged tooperate as and for the Purpose shown and set forth.

In testm ony that I elaim the foregoing as my own I have hereuntoaffixedmy Signature in pl'esenee of two Witnesses.
